A man in his late 20s has been arrested today in connection with the killing of a father-of-two earlier this year.
Peter Gunn went missing in the early hours of January 4th and was found murdered 11 days later. His remains were found at the side of Dunsoghly Lane in The Ward in north county Dublin.
A number of people have been arrested since the body of Mr Gunn was discovered.
The latest arrest took place in Castlerea, Co Roscommon this morning. He is currently being held under Section 4 of the Criminal Justice Act at Castlerea Garda station.
Mr Gunn died from stab wounds to his chest and back. It is believed the 28-year-old separated father was murdered elsewhere and his body then dumped in Dunsoghly Lane, off the old Finglas to Ashbourne Road.
Gardaí believe Mr Gunn was out in Dublin city centre on January 3rd and was last seen in the Summerhill area a few hours later.
